We got Danny as a rescue at 6 months, he came with "Queen Anne" legs, then at 18 months he was diagnosed with severe hip dysplasia and having seen his x-rays it was pretty bad. We were told to give him lots of road walks on the lead and keep his running to a minimum. Even on his last day, he trotted around the local park with Minnie and I but he hadn't eaten for 2 days and not poo'd for 3 or 4 days, he also had a very large lump in his throat. Due to this the vet felt she could not give him any more chemo and said she felt he only had days to live, would be in pain and suggested he be pts. It was an easy decision in the end, because in the couple of hours since I walked him, he had deteriorated so much he could barely walk and was looking at me as if to say "I've had enough, Dad". I vowed I would never let him suffer so we stayed with him as he passed away.
